Package: aptitude
Version: 0.7.3-1
Severity: normal
Dear Maintainer,
Searching a package which has a plus or minus symbol gives nothing.
For e.g. :-
$ aptitude search libstdc++6
$
This tells it doesn't know what to do with packages which have + or -
in their name.

Have you really tried it with a minus?
→ aptitude search zsh-dbg
p zsh-dbg - shell with lots of features (debugging symbols)

Sorry, that's not a bug, that's a feature! :-)
aptitude as well as apt-cache and apt use regular expressions for
searching. "+" is a special character in regular expressions and needs
quoting:
→ aptitude search 'libstdc\+\+6'
i A libstdc++6 - GNU Standard C++ Library v3
p libstdc++6-4.8-dbg - GNU Standard C++ Library v3 (debugging files)
p libstdc++6-4.9-dbg - GNU Standard C++ Library v3 (debugging files)
The only other character which is valid in a package names and a
special character in regular expressions is ".". But it stands for
"any character" in regular expressions and hence has less impact than
"the previous character can be present one or more times".
And JFTR:
→ apt-cache search g++ | wc -l
43150
→ apt search g++ | wc -l
WARNING: apt does not have a stable CLI interface yet. Use with caution in
scripts.
129647
→ aptitude search g++ | wc -l
18466
The numbers are different because apt-cache searches descriptions by
default, too, aptitude only searches in package names. And "apt
search" shows 3 lines per package and lists each package version
seperately. The three examples above show all packages with one or
multiple "g" in their -- or name or description.
Please reopen and retitle this bug report if you think that the
documentation on that is incomplete or if their should be a
commandline switch (or configuration option) to turn off regular
expressions for searching.
Regards, Axel
